Why not? You don't think it's a gen Miyota movement?
Actually this has been brought up as a possibility in general watch discussion, the AP section and over on rwg I believe. The cost for a gen 9015 is very low to start with, lower when a factory/maker buys in bulk. It may be just as easy to buy vs cost to make a clone movement of the 9015 is what I was gathering from reading the other threads I could find.
Maybe ask on of the TD offering this?
